This I believe is how certain aspects of the mind exists, information being temporarily stored and interactive with other systems. Theoretically then systems of the brain/mind should be able to be duplicated. This would allow for managing of large amounts of information, at very high speed, with no-heat generation. The only heat generated would be through the support systems / foundation - I suppose much like how the…

Not sure if you meant to imply the brain is an inherently quantum system or not, but if so: > Theoretically then systems of the brain/mind should be able to be duplicated. http://en.wikipedia.org/wiki/No-cloning_theorem It's actually theoretically impossible .

Interesting. I wasn't implying it's a quantum system, not through entanglement anyhow. I'm not sure it would need to be linked in such a way for it to play its role in overall functioning.

"For qubits, they can hold a value of “1” or “0” as well as both values at the same time. Described as superposition,"... Am a bit frustrated reading that same description for years and still having no clue what it really means. Both values at the same time... huh? What is the physical property that is existing in two states at once? And how does that feature translate into speedier computation? Is it so hard to unde…

Think of it like this. What if you represented your computer bits as a arrow on a compass. You have also the plane that the compass is on. The arrow points in one direction for 1 and in another direction for zero. Regular computation would have you doing operations on bits. You could only do one operation at a time on one bit and you are able to flip them given a recipe. A probabilistic computer allows you to do some…

You need to take more math before can understand this...start with some Linear Algebra to understand what a qubit is, maybe some abstract algebra to understand why fields are important, and then topology.
